Apparently I can't post a link. I bought a 3500mha battery on eBay. Lasts twice as long from limited testing and the cover fits perfectly. Only $10 so pretty happy. Maybe I can PM or email the link if anyone is interested. I would not waste your cash on one on the expensive brands. They are more than likely all made in the same Chinese factory.

I had bought a andida 1980mah batt from obostore. she is realy nice. reallife performance is +~20%. (deliver to germany, 14days)

1h ago i bought a 3500mah + cover version :) i thin the reallife performance is +50-60%
[LG Optimus 3D] borgqueenx:
do let us know when you have it if that 50% is real. i bought it from the UK so im getting it a bit faster then shipping from hong kong.
[LG Optimus 3D] vilks:
do u like then your phone is bigger with 3500mah?

but yes, original battery crap;/ i want that i could play games all day without recharge, for example.
[LG Optimus 3D] saint_cow:
Been using one of the eBay 3500 batteries for a few days. It lasts at least 50% longer. I removed the plastic clip/holder from my leather flip case and glued the case (without the holder) onto the new back cover. Fits perfectly.
[LG Optimus 3D] borgqueenx:
The ebay extended 3500mah battery has about 50% more life then the original battery. but the first charge it only has like 20 or 30% extra.

For 15 quid I got a 2500mAh battery from ebay. Been using it for 2 months now and I must say it has just started to wear down and now only last a few hours longer than the original battery. Before this though, it was lasting a good 2 days of low to medium use or for higher use I managed to get 5 3D films played one after the other for about 85-90% battery. Each film was roughtly 1 and a half hours long.

Hope this is useful.

Found this on ebay

Search ebay australia for this ... J67-Extended-Battery-LG-P920-P925-3D-THRILL-4G for $10.92

I have been using one of these for a couple of weeks and have noticed that it definitely last longer than the stock battery takes longer to charge too. The back case that is supplied fits real well too.

I was actually quite surprised with the quality and length of charge it has given me.

Really suggest you try it if your like me and live on your phone.

[LG Optimus 3D] Magxmushroom:
My opinion goes with wilso_sony because no genuine battery will make your phone go slower over time and also there is a internal switcher that detects the phones drainery and usage of the battery and also reads the internal statery of the battery so if you woud brick your phone your warranty will be gone!!!! if u wanna play games whole day or play movies buy a psp or a gameboy lol

EDIT: You can extend your battery life by recharging it before it reach the 5%

profile dont believe in battery training because the newer batteries dont work like that anymore THEY HAVE NO MORE MEMORY GAPS!!
[LG Optimus 3D] asterix29:
I have an extended battery 3500mAh + cover and really lasts about twice as stock.

I buyed with 23 euros from "batteryupgrade". I want to say that all battery's are produces in China, including stock, for Europe Lg's at least.

For example: Last night (aprox. 11 PM) it was at 87% and in the morning (aprox. 8:30 AM) is 85%, so only 2% consumtion

With stock battery, consumtion is at least 10% after night, dont know why :(

With heavy usage (games, movies, wi-fi) it last around 7-8 hours, unlike stock 3-4 hours

Reporting about ProdiCell 1900MAh battery. Testing about week, surprisingly, phone lives longer for about 20-25% 0f time while active use. Using stock V21D, after night in stand by mode it still has ~95%, while been charged to 98. After watching 2D cinema for about an hour and 40 minutes, I still have 70-75%, think this is good result, no battery issue in general for me now.

And what about this type of battery -ecell GOLD 1930MAH FL-53HN? Does anyone have tried it? I really need one more battery but without big back cover. Can anyone post links from ebay europe? Thanks for future answers! Have a nice day!
[LG Optimus 3D] sandulea:
I looked at the double capacity batteries with back cover, but I saw too many problems for the equivalent of a single extra charge (can't use cases, fast decline of battery life, bigger and heavier phone).This is my choice on extended batteries for our device: Momax iPower Pro

8000mAh, ability to charge 2 devices simultaneously, wide range of compatible devices. The mirror part of the battery is the same size as the phone itself, the weight is lower than the phone + leather flipcase, the thickness is the same as the phone + flipcase. In other words, it's the same as carrying another phone around, lets you use any case you want, but it gives you 5 extra full charges. Not bad for less than 100$ new.

When it comes to urban needs I get by with the original battery for up to 3 days, so I got this one for bike touring expeditions, when I may have to survive a whole month without plugging into a socket. Further down the road I'll get a solar panel as well, then the phone will fulfill my dream of not having to attach itself to a wall socket ever again.
[LG Optimus 3D] Blu3Shark:
Interesting device, sandulea! It has also an solar panel? But, I think a backup battery is more suitable for my needs. Can anyone recommend a good one?
[LG Optimus 3D] ronstew:
Downside for cycling

For long distance cycling, there is a real disadvantage to the Momax iPowerPro. You cannot charge the iPower while it powers your phone. If you want to power a phone from a dynamo with this device between the dynamo and the phone, you are out of luck.

I know because I bought one today, and have tried it. It should last me 200 km with all my bells and whistles (gps, endomondo, fm radio, heart-rate monitor) running, and maybe twice that, but no more.

Motorola makes a similar device (P893) with less capacity that apparently can charge while being charged. Again, this is of benefit if you are running your phone off a dynamo.

[LG Optimus 3D] saint_cow:
Is it possible that on a particular rom that the phone will not recognise the size/capacity of an extended battery and drain it down to empty based on the stock battery size? Reason I ask is that in gingerbread my extended battery (3500mAh) lasted pretty much twice as long as the stock one yet now that I am using ICS roms it seems like they both drain at the same rate, it's like the extended battery lasts no longer. I tried a few non scientific tests and the battery doesn't last twice as long any more.

Im using XBSA v8 and my battery lasts about 7 hours but that is not enough.. once happened to me I dont know how , when I was using JB 4.1.0 my battery with bluetooth headset turned on for 5 hours lost 5 %.. It happened only one time. This confuses me
[LG Optimus 3D] boltthrower56:
They don't explode that's an exaggeration.

I've been using 2 extended batteries as portable chargers for at least 6 months maybe longer I don't remember , they didn't blow up yet.

Exploding Lithium-ion batteries are extremely rare and are not specific to any type of manufacture , it's usually about how they were used. If you try to charge it with 24 volts which will be denied by the circuitry from the battery but if it fails , it will heat up , thus expand and blow up due to excessive internal pressure. The batteries are air-proof because lithium reacts with air. There isn't any flame unless lithium gets in contact with water and the hydrogen exposed finds some heat source to blow up...

Making batteries isn't a job to do , knowing how they are manufactured I don't see how the Chinese people could screw up so much to make it blow up.

Need i remind you that , It happened with a Samsung galaxy s3 original battery and not a Chinese knock-off ?
[LG Optimus 3D] niko22225:
some of cheap batteries do that.. I saw in news just some days ago that fale duracell batteries exploded in warehouse after being shipped. anyway I hope youre not chinese I didnt meant to be offensive.. what battery are using how long does it lasts?
[LG Optimus 3D] boltthrower56:
No , I'm not Chinese . And as far as I know Duracell doesn't make lithium batteries or at least I haven't seen one in Turkey.

As I said it's extremely rare. How many batteries have you seen exploding ?

I'm using original LG battery and 2 extended "Chinese" batteries in parallel for the portable charger I made. It charges my phone at least 5 times before depleting. I'm telling you Chinese don't make crappy products , they make crappy knock-offs. Have you seen Xiaomi M2 smartphone ? It's amazingly good.

Also , MIUI is from china check it out.
[LG Optimus 3D] niko22225:
how many hours does your original battery lasts?
[LG Optimus 3D] boltthrower56:

[LG Optimus 3D] forfoxy:
right you. when I used 0.8A to discharge battery, the result was about 2800mAh, when I used 0.5A - about 2900. I suppose if I use 0.1A - the result will be abot 3300mAh
[LG Optimus 3D] niko22225:
Is 0.8A and 0.1A a voltage?

Sent from my LG Optimus 3D XBSA VR3D with AC!D Audio Engine
[LG Optimus 3D] :
Niko22225 - No. "A" is Ampere - the amount of electricity flow that have to work against the resistance of electrical circuit (as of Ohm's Law). "V" is voltage, however.

The Lithium : Cobalt Oxide battery (rather common type) typically feed the electronics at 3.6 Volts, while the original phone battery is designed to handle 1.5 Amps power (as printed on LG battery itself; 1500mAh = 1.5 Amps per hours that can be handled by battery until 3.0 Volts cut-off).

And, that's correct. Amp/hours is typically affected by the current consumption imposed by loads. I see that rather often when messing around with Lithium-ion batteries - if you draw very little power from battery, it improves runtime between the maximum possible printed on battery itself, but if you increase current, runtime is reduced - so battery choice for DIY electronics is rather important - measure twice, cut (or rather, solder) once.
[LG Optimus 3D] forfoxy:
100% correct. nothing to add.
[LG Optimus 3D] niko22225:
I didnt get it but I want to ask.does changing the ampere make a difference in battery life?

Sent from my LG Optimus 3D XBSA VR3D with AC!D Audio Engine
[LG Optimus 3D] :
Well, yes - at cost. You can easily get longer run time by increasing the battery's amperage handling capability. However, to maintain safety and consistency, it obviously have to be larger, enough to warrant the separate cover as necessary.

There is limit to how much you can squeeze before you actually compromise battery safety. So 3 Amps / hours is decent for the battery of doubled thickness - I will take thick battery over thin battery with crazy amperage rating on any day. I have seen Li-ion battery burst into flame with very little warning, and that happens quickly. Why so? That's a juggling acts between varying the amount of anode material (Lithium Oxide - Cobalt [Li:CoO] or other Lithium-based chemistry, in depleted state which represent the worst case of when it changes thickness - the most important parameter. Lithium : Iron Phosphate material thickness changes very little however) and separator thickness - separator is what make or break the battery and it's surprisingly thin.
[LG Optimus 3D] niko22225:
Well I'll just say I got really bad grades from chemistry :D

Sent from my LG Optimus 3D XBSA VR3D with AC!D Audio Engine
[LG Optimus 3D] :
XP LOL Well, that's mostly to give you the idea that it was done to balance the safety and capability of providing more oomph. I have been dealing with bare cells for as long as I know - safety comes first.

By the way - Lithium-ion batteries (of any chemistry, even 3.2 Volts Lithium : Iron Phosphate [Li:FePO4] one) are all pretty efficient as far as charging is concerned - they generate very little heat when charging, the only time they get warm is when they are near death (increased internal resistance - from age), or when electrically abused above its amp / hour rating.

You don't want to get to 60 - 70 C or hotter for Lithium : Cobalt Oxide battery, it will go downhill quickly (thermal runaway).
[LG Optimus 3D] boltthrower56:
Are you sure it was li-ion ? Lithium batteries explode or burst into flames if it comes in contact with water so it's rather easy because lithium is very reactive as it is an alkaline metal...

With li-ion though lithium is in some kind of solution which I know from my experiments , is not flammable. It should be quite rare unless you abuse the battery...
